Hi, Mike Marston here from Easy I/O. Eric Stromquist has dubbed me the Mad Scientist of Sedona, which I think is a compliment ( but not quite sure yet), and has asked me to share some thoughts regarding building automation controls as I travel across the world. In that I am a big fan of ControlTrends I agreed to post my thoughts from time to time.
So here goes. Something I have been thinking about a lot lately is Human Machine Interfaces or HMI’s in our industry. One of the first questions I would like to answer regarding building automation control systems is — what is the best Human Machine Interface (HMI) for our type of building automation controls projects and end user customers? While some customers require tablets, touch screens, iPads, iPhones, Androids, and HTML5 (where will it stop?), these devices might not be well suited for all maintenance personnel. So what is the best solution for a building controls system integrator to leave for the customer to interface with the control system you have installed.
There is an incessant challenge to structure and present content that is both easily readable by humans, via graphics and dashboards,yet consistently understood by the machines that run them. In any case, the user must find the data or the data must find the user.
Remember, the primary concern is to ensure that the customers have an adequate human machine interface, and I think in all cases, it is best to keep the HMI solution as simple and efficient as possible.
So ControlTrends community, which HMI are you using and what benefits and challenges do they offer? Please let me know your thoughts in comments and if you have any questions about Easy I/O or the Sedona framework please feeL to post them in the comments section and I will get you an answer.
Until, I get to post again, this is Mike Marston, the Mad Scientist of Sedona signing off, and remember when it comes to great DDC controllers they call it EASY I/O for a reason.
